Fluid Flow Switch, SPDT

F61

The F61 Series Flow Switches are Single-Pole, Double-Throw (SPDT) flow switches used on fluid lines carrying water, ethylene glycol, or other fluids not classified as hazardous. They can be wired to energize one device and deenergize another device powered from the same source when fluid flow either exceeds or drops below the set flow rate.

The F61MG type flow switches are used for low-energy loads to operate small relays, solenoid valves, and electronic control circuits. These flow switches have gold-plated contacts for improved electrical performance in low voltage, low current circuits.

• Stainless steel paddle has three segments for use in pipes from 1 in. to 3 in. (25 mm to 75 mm) diameter • Paddle segments can be removed or trimmed as needed • F61KB-11 and F61MB-1 include a 6 in. (152 mm) paddle for pipes 4 in. to 6 in. (102 mm to 152 mm) • Gold-plated contacts on F61MG-1 reduce intermittent contact problems in low-voltage and low-current circuits
